IMPROVEM ENT IN STUFF-REGULATORS .FORPAPER-MACHIN ES.

Specification forming part of Letters Patent No. 168,746, dated October 11, 1875; application tiled March 15, 1875.

regulation of flow of the paper pulp or stuff.

from the pulping machine to the paper-machine automatically and correctly, thereby doing away with the service of attendants and insuring greater accuracy.

My invention consists of a float arranged Within a tank or vat, and connected with a sliding or shifting plate by a combination of levers and other mechanism, in such manner that as the float rises upon theinflowing pulp or stuff, the inlet of which is located directly beneath, the rising of the float will communt cate movement to the plate which governs the outlets, so thatthe outflow of the pulp is regulated on its way to the papermachine, or its excess diverted therefrom and directed to the reservoir, as desired, automatically. It also consists in a combination of a disk or wheel, provided with holes or graded apertures, said disk arranged in combination on the one side with the shifting-plate, through the medium of cogs, and on the other side with the lever giving the movement, in such mannerthat the amount of throw or shift of the sliding plate may be regulated.

Figure 1 is a perspective View of machine. Fig. 2 is a horizontal View or plan. Fig. 3 is a lengthwise section of machine.

There are two sheets of drawings, marked respectively Sheet 1 and Sheet 2, and upon which a represents the side walls of the tank. 1) represents the end walls, and c the bottom. 61 represents a partition running entirely across the tank, and eis another partition at right angles therewith. The partitions d and e reach upward from bottom of tank to about half the height, although this'might be varied to suit circumstances, and these partitions divide the tank into three chambers, f being the larger, and the two remainder or smaller chambers I have marked g and h, respectively. The inlet-aperture is in bottom of large chamber, and the outlet from the same chamber is over partition (1, and the outlet leading from the tank to the paper-machine is in the center of the bottom of the small chamber g, and the outlet leading from the tank to the reservoir is in the center of bottom of the small chamber h. At t is shown the float, constructed in any suitable manner, so as to rise properly on the surface of the int-lowing mixture. At j is a half-case or guide-frame attached to the bottom 0 of the tank. Its object is to guide the float as it rises vertically. At It is shown an arm attached to top of tank,

pivoted at k, and, reaching upward to a suitable height, is pivoted to a lever, l, which lever is sustained at about its center by the standard The standard, resting upon the adjustable crosspiece m is secured to the sides of tank at m, in any suitable manner. At the outer end of lever l is fitted a slotted plate, a, or its equivalent, into which runsone end of anotherlever, o, placed at right angles therewith and sustained at its outer end by a standard, 9, running upward from side of the tank. The lever 0 has beneath, at the point where pivoted to standard, an arm, 0 reaching downward to nearly the top of tank, where it is connected to another arm or lever, 0 which reaches over to the center of tank, to where it connects with a revolving disk, q, or wheel, perforated so that the connection may be adjustable. The axle g of, the said disk or wheel q runs lengthwise the tank, resting upon end of tank, and its opposite end resting upon cross-bar m by suitable bearings. At g on the axle g cogs are arranged, fitting to corresponding cogs 1' .on the sliding plate s, in such manner that as the cogs 'r are revolved with the wheel or disk q the sliding plate 8 is slid from side to side, as desired. The shifting or sliding plate 8 is provided with friction-wheels t, running upon rods or rails u and a, so as to run readily. The eX- act distance traversed is regulated by the manner in which the connection of lever 0 is arranged to the disk q, the said disk g being provided with a series of holes through, and at suitable distances and di ections from, its center, into which the turned'end of lever 0 may be run or hooked, giving the requisite adjustability desirable.

The operation of the above-mentioned devices is as follows: After lever o is adjusted and connectediproperly-to the disk q,:the machine is ready-for'the inflow of the paper pulp or stuff, which enters beneath, the float 13, through inlet, causing the fl'oat to rise, which it continues .to do to the exact extent of the rise of the inflowing mass, in its rise-moving upward the end of lever l, attachedto floatarm k, depressing the opposite end of lever l, carrying with itthe connecting end of lever o, and, through said lever 0, its down ward-projecting arm 0 and lever 0 revolving the disk q and cog-wheelr, communicating a sliding motion to the plate or slide 8, according to the manner of ajustability of lever o with disk q. l

The sliding plate 8 fits against the partition at, over which the pulp must pass, and by its sliding backward orv forward along the said partition ,forces; or diverts all excess of flow of ,the pulp from the chamber leading to the paper-machine to that leading to thereservoir. Thereby the exact amount is regulated, and any overflow toward the paper-machine prevented. The pulp, being a thickeuedmass, is

liable to" overflow the machine were this precaution not taken. r

-Dotted lines on Fig. 3, marked w, show a modification of the contrivances before men-' tioned, by which the lever 0, arm 0 and the standard 1) are dispensed with, and the lever 0 by having its outer end connected with lever l in any suitable manner, creates a more direct connection between the tank float i and the wheel q or disk, and in some cases thisconnection is veryuseful; but in large tanks the first-mentioned combination is the best.

What I claim as new, and desire to secure by Letters Patent of the United States,-is-

1. The combination of float 6, arm k, lever l, cr0ss-1ever 0, arm 0 lever 0*, disk q, cogs g and r, and shifting or sliding plate 8, in the manner substantially and for the purpose described and set forth.

2. The combinationof disk or Wheel q, shifting-plate s, and lever Z,constructed andfar ranged to' operate substantially in manner and for-the purpose described and set forth.
